For the first time of my life, I attended a technical seminar given by one of my favorite oracle experts: Tom Kyte
If I have one thing to emphasize about this seminar it will be the modesty of Tom Kyte. He is so humble and modest so that he can make your stupid question an interesting issue to explore. I have pointed out that he never refused answering a question during the break time despite that he would much appreciate to take this break time to send e-mails or to answer other urgent questions coming from another place of the world.
This is another proof that a fundamental skill of a great specialist regardless of its domain specialty is its modesty.
It was about bind variables and cursor sharing, storage techniques, indexing, reorganizing objects, materialized views and cashing, and Q&A as always.
